Google Inc. has acquired solar-powered drone maker Titan Aerospace as the internet search giant ramps up plans to deliver wireless internet access to remote parts of the world, Reuters has reported. The deal comes several weeks after rival Facebook Inc announced plans to build solar-powered drones and satellites capable of beaming internet access to underdeveloped parts of the world. Titan is developing a variety of solar-powered “atmospheric satellites,” according to the company’s website, with initial commercial operations slated for 2015. The drones, which fly at an altitude of 65,000 feet and can remain aloft for up to five years and have a 50-metre wingspan, slightly shorter than that of a Boeing 777.
